Dipel electronics presents a series of ultrasound doppler, a unique solution for detection of foetal heart at 10 to 12 weeks. These doppler not only detects foetal distress & intrauterine death but determine multiple pregnancies as well. Very low intensity ultrasound of frequency 2 mhz is beamed in to body from a very small transducer, which is reflected back from organs & blood particles. Reflected signal is changed slightly in frequency due to movement of foetal heart, blood particles & other moving organs. The instrument receives, amplifies & electronically processes the reflected signal to get audible signal through built in speaker or external earphone. It provides a facility for earphone & tape recording. It operates on 6 dry cells eveready 1050 type or can be operated on main supply with mains adapter. Dipel electronics pvt. Ltd. Also manufactures a complete range of ultrasound doppler products for obstetrics, pediatrics, vascular/arterial and neonates applications.
